Do you see your cabinet in the kitchen separating from the wall? Do you ponder to find its reasons? Well, it can be mainly for two reasons. First, improper cabinet installation and sagging due to water; the cabinet may fall apart from the wall. Also, putting too much weight on it is harmful.

Improper installation and low-quality material:

Typically, screws and studs are used to hang the cabinet with the wall. The screws must go through the studs and connect with the wall properly. However, at times the installer may miss hitting the studs. Or, he may only use screws on the edges.

Finally, the screws and the studs can be of poor quality. As it happens, the screws start falling off, and the cabinet becomes loose. It will then start separating from the wall.

Excessive sagging:

Kitchen sink cabinets are meant to stay close to water. Thus, they become wet and remain damp for an extended period. When you use poor-quality wood for the cabinet, it will start sagging soon. As the cabinet starts softening and sagging, it will come from the wall.

  • 1-1/2-inch screws
  • 1/2-inch plugs
  • 120-grit sandpaper
  • Miter saw
  • Hammer
  • Chisel
  • Stain marker

Step 1: Removing the residues

Carefully insert the putty knife between the separating cabinet and the wall. Find the cracks, separated parts, and joints. Clean the residues from them with the putty knife. Next, you must remove the wood chips, debris, and glue from the wall.

Step 2: Prepare the studs

When reinstalling the cabinet, you have to use new studs. For this, you must get an accurate measurement. You may follow this process:

  • Get the cabinet against the wall by forcing it back to its original position.
  • You must measure the distance between the countertop head and the cabinet bottom. As you measure the distance of the gap, seek help from a friend or family member to hold the cabinet firmly.
  • Sometimes, there might be no countertop available. At this moment, measure the gap from the kitchen floor. Then, add ½ to it. Finally, use the miter saw to cut the studs accordingly.

Step 3: Mount the studs

Remember the cracks and joints that you cleaned beforehand? Now, it’s time to apply glues on all these cracks and joints, so they are filled in correctly. Then, reach the front of the cabinet underneath it. Use the hammer to tap the stud’s bottom forward. It will pry the cabinet appropriately right on the front for further installation.

It will help tighten the studs and cabinet with the back wall.

Step 4: Reinforce the joints with drills

Before you apply the screws with the studs and cabinet, you must reinforce the joints. It helps the joints and cabinet stay in proper condition for longer. Use the cordless drill and 3/16 inches drill bit to drill the cabinet front.

You must carefully drill only at the joints, separations, and cracks. Also, drill the joints on the sides and shelves for better reinforcement. Then, use the ½ inches Fostener drill bit for the countersink to drill ¼ inches on the ball joints again.

Step 5: Apply the screws

Now use the cordless gun to apply the 1-1/2 inches screws to the holes. Tighten them appropriately so they don’t come loose. For the countersink holes, apply glue to them. Then, find the wood plugs and tap them in the holes.

Tap the wood plug with the hammer to ensure it reaches the bottom.

Step 6: Tighten the screws and studs

First, you must find the installation screws on the wall and cabinet. For this, lean on the kitchen cabinet carefully. Then, looking back at the cabinet, you should find a wooden rail. It will be right on the top of the cabinet top.

If you see closely, you will find two to three on the wooden rail. You must reinforce it by driving one screw on either side of the existing one. You can use the cordless gun to drive the screws and tighten them carefully.

Repairing a cabinet that is coming apart from the wall is relatively easy. First, you must drive the screws until it hits the studs. Then, you can tighten it slightly before stopping.

Step 7: Finish off the repair project

You must allow the glues to stay for 24 hours at least. It helps the glues set correctly and better hold the screws and joints. Then, look for the excessive part of the studs and trim them with a chisel carefully. Also, you must chisel the wood plugs too.

Finally, sand the plugs to smoothen them with 120-grit paper.
